> I've never remotely wanted anything similar to this in Vue,
This was true of me as well until actually playing more with React. In practice, being able to very quickly extract a child component by just copying a chunk of code to a different spot in the same file is a very nice workflow benefit I now sorely miss when using Vue. In Vue my components tend to be larger and more complex than they are in React because I feel like some small extraction I want to make doesn't "deserve" it's own dedicated file, whereas in React I just quickly make a new function that returns some JSX and I'm done.
